Hi, I have the Krivo Humbucking Magnetic Upright Bass Pickup. (the old bigger model) I love them! Problem is that after a few months of playing, I start getting a buzz. I have 2 of them because I never know when they are going to start buzzing. When the first one went out, I purchased the spare with the intention of fixing the other. Now I have two buzzing Krivos. Does anyone have any experience with this? I have zero electronics ability, Im colorblind so never had a chance to really get into electronics. The Pickups do see alot of use. I do about 100+ shows a year. I remove them after every show and keep them in a protected box inside a protected case. I try to make sure the wire is always supported and never hanging. I guess Id like to get some ideas where its failing and what could I possibly be doing wrong. Im in Colorado so if anyone with the proper skills would like to look at them and make a little extra cash fixing them, please reach out. Thanks!
